8205.59.45.00 - Caulking guns

This HTS classification, 8205.59.45.00, specifically designates caulking guns constructed from iron or steel. These hand-operated tools are designed for the controlled application of sealants, adhesives, and other viscous materials commonly used in construction, automotive repair, and DIY projects. The primary function of these tools is to dispense material from a cartridge or tube in a consistent and manageable stream.

While this category is nested under "Other handtools (including glass cutters) and parts thereof: Other: Other: Of iron or steel," it is distinct from its sibling, 8205.59.55 ("Other"). The key differentiator lies in the specificity of "caulking guns" versus the broader, residual classification of "other" handtools made of iron or steel that do not fit into more precisely defined categories within heading 8205. Therefore, if an iron or steel handtool is not a caulking gun and does not fall under any other subheading within 8205.59, it would likely be classified under the sibling category.

As this HTS code is a leaf node, there are no further subcategories. Classification under 8205.59.45.00 is based on the definitive identification of the item as a caulking gun made of iron or steel, fulfilling the specific requirements of this subheading.
